Abstract (en)
[origin: EP0388243A1] Disclosed is a polyamide/polybutadiene/acrylonitrile block copolymer which comprises a polycondensate comprising a polybutadiene/acrylonitrile copolymer having a carboxyl group at each terminal thereof and a polyamide having an aminoaryl group at each terminal, and which is represented by general formula (I) <CHEM> wherein R is a divalent organic group, Ar is a divalent aromatic group, x, y, z, m and n each represent mean degree of polymerization and are integers in the ranges of x = 3 to 7, y = 1 to 4, z = 5 to 15, n = 1 to 30, and m = 2 to 20, respectively. Also, disclosed is a method of producing the polyamide/polybutadiene based block copolymer by polycondensing an aromatic diamine with an aromatic dicarboxylic acid to form a polyamide having an aminoaryl group at each terminal thereof, and then polycondensing it with a polybutadiene/acrylonitrile copolymer having a carboxyl group at each terminal thereof, preferably in the presence of an aromatic phosphite and a pyridine derivative.
